A limit low on your Watlow Controller can indicate: * The temperature is less than the limit set point. Check the cause of the under temperature. * Limit outputs latch and require reset. Clear limit. * Incorrect alarm set point. Establish correct limit set point.
What does limit high mean on my Watlow F4T?
A limit high on your Watlow Controller can be due to: * The temperature being greater than the limit set point. Check the cause of the over temperature. * Limit outputs latching and requiring a reset. Clear the limit. * An incorrect alarm set point. Establish the correct limit set point.
What does alarm low mean on my Watlow F4T Controller?
An alarm low on your Watlow Controller can indicate: * The temperature is less than the alarm set point. Check the cause of the under temperature. * The alarm is set to latching and an alarm occurred in the past. Clear the latched alarm. * The alarm set point is incorrect. Establish the correct alarm set point. * The alarm source is incorrect. Set the alarm source to the proper setting.

Check the cause of the over temperature. * The alarm is set to latching and an alarm occurred in the past. Clear the latched alarm. * The alarm set point is incorrect. Establish the correct alarm set point. * The alarm source is incorrect. Set the alarm source to the proper setting.
What does limit error mean on my Watlow Controller?
A limit error on your Watlow Controller can be caused by: * A sensor improperly wired or open. Correct the wiring or replace the sensor. * An incorrect setting of the sensor type. Match the setting to the sensor used. * A corrupt calibration. Check the calibration of the controller.
What does error input mean on my Watlow F4T?
An error input on your Watlow Controller can occur due to: * A sensor improperly wired or open. Correct the wiring or replace the sensor. * An incorrect setting of the sensor type. Match the setting to the sensor used. * A corrupt calibration. Check the calibration of the controller.
How to troubleshoot no serial communication on Watlow Control Unit?
To resolve a 'No Serial Communication' issue with your Watlow Control Unit, ensure that each device on the network has a unique address. Verify that the protocol, baud rate, and parity settings match between all devices. Check for any wiring issues and inspect or replace the converter if needed. Ensure the communication port is correctly set up and that the software setup matches the controller's configuration. Keep communication wires away from power wires and place a 120 Ω resistor across EIA-485 on the last controller.
How do I clear or reset the limit on my Watlow F4T Controller?
If the limit on your Watlow Controller won’t clear or reset, it could be due to: * The sensor input being out of the limit set point range. Correct the cause of the sensor input being out of the limit range. * The limit set point being incorrect. Set the limit set point to the correct trip point. * The digital input function being incorrect. Set the digital input function and source instance.
What to do if the alarm on my Watlow F4T Controller is not working?
If the alarm on your Watlow Controller won’t occur, consider these potential causes: * Alarm silencing might be active. Disable alarm silencing, if required. * Alarm blocking might be active. Disable alarm blocking, if required. * The alarm might be set to an incorrect output. Set the output to the correct alarm source instance. * The alarm might be set to an incorrect source. Set the alarm source to the correct input instance. * The alarm set point might be incorrect. Set the alarm set point to the correct trip point. * The alarm might be set to an incorrect type. Set the alarm to the correct type: process, deviation, or power.
Why doesn't my Watlow F4T process control to the set point?
If the process doesn’t control to the set point on your Watlow Controller, it could be due to the following reasons: * The controller might not be tuned correctly. Perform autotune or manually tune the system. * The control mode might be incorrectly set. Set the control mode appropriately (Open vs Closed Loop). * The control set point might be incorrect. Set the control set point in the appropriate control mode and check the source of the set point: remote, idle, profile, closed loop, open loop.
